Cronos appeared as guest vocalist for Enthroned on Towards The Skullthrone Of Satan, on Hammerfall's Chapter V: Unbent, Unbowed, Unbroken (on "Knights Of The 21st Century") and on the Probot CD.

He also did backing vocals on Cradle Of Filth's Dusk and Her Embrace (on "Haunted Shores") and Massacre's Inhuman Condition.

There are no ever-present members in the Venom line-up. The only original member currently in the band is Cronos. The band briefly split after Calm Before The Storm (recorded without Mantas) before reforming without Cronos. They split again after The Waste Lands and later reformed with the classic line-up, though Abaddon and Mantas have both dropped out over the years.

Illness and passport problems prevented Jeff "Mantas" Dunn from joining the early part of Venom's At War With Satan US-tour. He was temporarily replaced by Dave Irwin and Les Cheetham.

Cronos switched to bass when Alan Winston left the band a week before a gig - his decision to plug his bass guitar into a guitar amp is credited with the development of his trademark "bulldozer bass" sound. The line-up was further trimmed down to a three-piece following the first demo session when the rest of the band decided they prefered Cronos' vocal style to Archer's.

Originally began as a 5-piece called Guillotine with Clive Archer on vocals, Alan Winston on bass and Cronos on rhythm guitar. Archer and Mantas met at a Judas Priest concert in 1979 which led to Archer and Abaddon (both of the band Oberon) joining Guillotine.
